hi bro, thank you for your comment. Error e020 occur when there is no toner in our developer / hopper tank. Please make sure there is enough toner inside. And if there is still error after adding some toner, please check/ clean the sensor inside and make sure there is no gear failure in the hopper tank. Sorry for not explain it in english, . Im not a technician, but in my case i found the temporary fix by adding toner manually inside developer. Cheers !
You do nothing for err020
